' The timer is shown as a plied .ito an. fiengin'e' having atiming-sha :5 -and-engine casing 6; the latter proyided with-theiisual centering ring coaxlali-witlr-"the timing shaft 5.

Fixed on the timing shaft is-a =-bracket collar 18 provided with e pair of perforated brackets 19, between which are pivotally mounted'a pair of fork members QQ forming Applie atlon' tile'd Jol y- 2 2,
